Emergency shower units (ESUs) are responsible for human safety in production facilities. They are similar to a regular shower, but their main feature is instant action, high water supply pressure, and maximum convenience for employees. These are professional installations and are not intended for home use. They differ from ordinary shower cabins in their external structure, dimensions and price.

What is it?

Emergency shower is efficient system emergency eye and body wash, designed for large industries and chemical laboratories. On at the moment They produce emergency showers for the eyes, bodies, combined installations, frost-resistant, with additional heating, fountains. ADU is a means of collective defense that provides first aid to the victim. With its help, aggressive chemicals are quickly removed from the skin and mucous membranes, thoroughly washing them.

ADUs are made from durable materials. Most often it is galvanized steel. A standard simple emergency shower is attached to a vertical surface, such as a wall. It is equipped with a manual lever. More complex and professional installations are made in the form of booths that are protected from radiation.

Emergency shower for eyes

Specialized AUVs, depending on their purpose, help in the most difficult situations and conditions. Emergency shower for eyes - an installation that is equipped with a special manual activation pedal and mixer. After an emergency occurs, the victim must press the emergency shower pedal.

The peculiarity of the devices is that they are constantly connected to the water supply, and when starting, the valve opens and sprays liquid under pressure in the desired direction. Emergency shower units are protected from deformation and corrosion, so they last a long time.

Installation Requirements

Emergency showers should be installed in all potentially hazardous production facilities where there is high risk contact of human skin with caustic substances such as acid and alkali. The categories of dangerous places include:

• Warehouses for storing chemicals.
• Laboratories.
• Foundries.
• Treatment facilities.

Requirements for the installation of emergency shower cabins are written down in regulatory and technical documents that are valid in Russia. For example, they are recorded in sanitary rules « Hygienic requirements to the placement, design, construction, operation and repurposing of chemical weapons destruction facilities, and the decommissioning of chemical weapons storage facilities.” Emergency showers must be connected to the water supply and located in the most convenient place for the enterprise employee. The victim must use the ADU no later than seven seconds after the emergency occurs.

Emergency shower refers to technical means collective defense. Another name is emergency decontamination shower. Its purpose is the emergency removal (washing away) of chemically aggressive and other types of hazardous substances, microorganisms that got onto protective clothing as a result of an accident, skin, on the mucous membrane of the eyes, nasopharynx. Such souls are also installed in production premises(workshops) where clothing may catch fire.

Protective effect

Timely removal of harmful substances from the surface of clothing and open areas of the body, extinguishing tanned workwear significantly reduces injuries at work, reduces the likelihood of severe injuries and deaths.

Structurally, a decontamination shower can consist of one or several pipes with built-in spray nozzles. The opening of the water flow is carried out by pressing one control element, which can be, for example, in the form of a lever or a rod. Home functional feature such a shower is the creation of a powerful volumetric flushing flow of water that can quickly (less than 2 minutes) remove a hazardous substance from the entire surface or extinguish a fire.

Anti-corrosion protection

Since the emergency shower is installed in close proximity to a hazardous object, it is exposed to chemicals during operation active substances. High reliability of the decontamination shower is ensured by the use of anti-corrosion protection of the structure. In particular, critical parts can be made of stainless steel and brass. Ferrous metals necessarily have a durable protective coating, resistant to acidic and alkaline environments, salts, solvents, lubricants.

What regulatory documents stipulate the requirements for self-help devices (emergency shower and self-help sink) in industrial premises and outdoor installations, namely: - water temperature for self-help devices; - distance from the workplace with chemically hazardous substances to the self-help device; - distance between self-help devices; - time during which it is necessary to use the self-help device; - uninterrupted water supply to self-help devices (the need to install additional water tanks and pumps). References to regulatory documents are required. Thank you.
